Many parts of the Front Range urban corridor have had 10-11 days without a frost or freeze and gardens are coming to life. But don’t be fooled. Not only does climatology suggest that the last freeze in Denver-Boulder-Fort Collins is typically in early May, but today’s weather maps strongly suggest a cold period beginning Sunday evening and continuing until midweek. We will probably see widespread freezing temperatures during at least one morning in that stretch. There is also a chance for one of more periods of cold rain giving way to wet snow even in the lower elevations (possible heavy amounts in the mountains) in the Sunday night through Tuesday time period.
Until then the weekend should be relatively mild and dry. But be prepared for some afternoon/evening showers or thundershowers scattered around today and again on Saturday.
